<title>Double-pass system with unequal entrance and exit pupil sizes to measure the optical transfer function of the human eye</title>

Abstract

We propose a new version of the double pass apparatus with unequal entrance and exit pupil to measure the complete optical transfer function in the human eye. This system overcomes the limitation of the double pass technique with equal pupil sizes where phase information and odd asymmetries are lost in the double pass images (Artal, Marcos, Navarro and Williams, J.Opt.Soc.Am.A., 1995). By using the asymmetric double pass apparatus with different entrance and exit pupils, one of them small enough (usually the entrance pupil) to consider the eye diffraction limited, the complete optical transfer function of the eye, including the phase transfer function, and the shape of the point spread function are determined.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
